JOSEPH LATITENBURG, OF NEW YORK, N. Y.

TOBACCO-PIPE.

Application filed February 2, 1915.

To all whom it may concern:

Be it known that I, JOSEPH LAUTENBURG, a citizen of the United States, residing at 270 Grand street, New York, in the county and State of New York, have invented a new and useful Tobacco-Pipe, of which the following is a specification.

My invention relates to improvements in tobacco pipes, and it consists in the novel features hereinafter more fully described.

The objects of my improvement are: First, to provide a tobacco pipe, which is sanitary and which can be kept free from the accu mulation in its passages of nicotin and of tobacco smoke deposits. Second, to prevent the body of the pipe from getting impregnated with nicotin and the odor of burned tobacco. Third, to have the same tobacco pipe simple, durable and inexpensive. I attain these objects by the tobacco pipe, two forms of which are illustrated in the accompanying drawings, or by any mechanical equivalents or obvious modifications of the same.

In the drawings Figure 1 is a longitudinal section of my tobacco pipe; Fig. 2 isan elevation showing the stem 14 with the threaded extension 15 of the lining channel 15. Fig. 3 is a side elevation of the inner removable smoke tube or duct 16. Fig. 4 is an elevation of the tapered and tapped ferrule 13 which is shown in Fig. 1 as located in the neck 12 of the tobacco pipe. Fig. 5 is a section of a slightly modified form of the bowl 21 and neck 22 of my tobacco pipe with its tapped ferrule 23 in position. Fig. 6 is an elevation of the form of the stem 24, adapted to fit the neck 22 of the tobacco pipe shown in Fig. 5, with the smoke tube or duct 16 partly drawn out of the stem 24. Fig. 7 is an end projection of the stem 14 shown in Fig. 2; Fig. 8 is an end projection of the smoke tube or duct 16 shown in Fig. 3. Fig. 9 is an end projection of the tapered ferrule 13 shown in Fig. 4. Fig. 10 is an end projection of the stem 24 shown in Fig. 6, With the smoke tube or duct 16 removed.

Similar numerals refer to similar parts throughout the several views.

11 is the bowl of the form of my tobacco pipe shown in Fig. 1; 12 is the neck of the same; 13 is a ferrule secured in the neck 12, and shown in Fig. 1 as tapered on the outside and tapped. 14 is a stem shown as extending from the mouth to the neck of the pipe and having permanently connected Specification of Letters Patent.

thereto a lining channel 15 of any suitable material; 15 is the threaded end of the said lining channel 15, which extends beyond the stem 14 and which forms with said tapped ferrule 13 a connection for said stem 14 and neck 12. The ferrule 13 may be jammed or driven into its seat in the neck 12. 16 is a smoke tube or duct having a sliding fit inside of said lining channel 15 and extending from end to end of the same; 17 is the beaded end of the smoke tube or duct 16.

The smoke tube or duct 16 is removable. When it becomes fouled it can be readily replaced by another similar smoke tube or duct; or the same smoke tube or duct may be reinserted after having it washed or cleaned.

The form of the ferrule 23 shown in F ig. 5 is cylindrical, and it can be inserted through the bowl 21 of the tobacco pipe; it may also be made tapered in a direction contrary to that shown in Figs. 1 and 4.

The neck 22 shown in Fig. 5 is longer than the neck 12 shown in Fig. 1, and the stem 24, which is adapted to fit the neck 22, is correspondingly shorter than the stem 14.. which is designed to fit the neck 12. I

The lining channel 25 is shown in Fig. 6 as extending beyond the stem 24, and it is designed to be inclosed by the neck 22 when the tobacco pipe is assembled.

25 is the threaded end of the lining channel 25.

26 is a gland at the end of the stem 24, which gland may be formed of the same material as the stem 24, and it is designed to fit the enlargement or box 27 in the neck 22 of the tobacco pipe shown in Fig. 5.

The thicknesses of the sundry parts of my tobacco pipe are exaggerated in the drawings for the sake of clearness, particularly the thickness of the stem and that of its lining channel.

It is evident from the drawings that the lining channels 15 and 25 will prevent the smoke from coming in contact with the body of the neck and stem of the pipe; also that, by removing the smoke tube or duct 16 when it becomes fouled and replacing it with a clean one, the accumulation in the pipe of nicotin and the accompanying bad taste and odor will be avoided, and the pipe will always be both sanitary and agreeable. It is also evident from the drawings that the two members 15 and 16, forming a double lining for the stem 14 and neck 12 of my tobacco pipe throughout the length thereof, will afford an ample barrierto the passage of any deleterious gases or odors from the inside of the bowl 11 or duct 16 to the body of said neck 12 and stem 14. The presence of a thin film of air. between the outer surface of the duct 16 and the inner surface of the channel 1515 will increase the resistance to the passage of any gases or odors therethrough.

This resistance will also be augmented by the. surface tension of the two linings, which are shown as extending throughout the length of the stem 1% and neck 12 to the inside of the bowl 11. The ferrule 13 is also shown as extending to the inside of said bowl, leaving no chance for any gases or odors to Work their Way in between the lining 1515 and the body of the neck 12 or stem 14. The suction on the duct 16 will produce a tendency of the film of air, inclcsed between the linings 15;15 and 16, to flow toward the bowl 11, rather than in a contraryv direction.

I do not wish to restrict myself to-any particular size or shape of the component parts of my tobacco pipe, nor to the material of which they are made. Many mcdi-' fications could be made in the design of the details of my tobacco pipe without departing from the main scope of my invention;

also only some of the parts of my tobacco pipe may be used, and some of its advantages may be gained thereby; thus, the smoke tubeor duct 16 may be omitted, and

the lining channel 15 or 25 may then be cleaned when necessary; or the lining channel 15 may be left out, and the smoke tube or duct 16 may be connected to the neck 12-. The means of connecting the lining channel 15 to the neck 12 may be varied; the smoke.

tube or duct 16 may also be provided with a spring or catch to secure it in the lining channel instead of its being held in place by friction, as it is in the forms disclosed by the drawings. I do not therefore restrict myself to the forms and arrangements of duct inclosed by said channel, said duct extending from end to'end of said channel and havlng a slidmg fit therein, and a ferrule in said neck, extending to the lnside of said bowl, said ferrule being adapted to connect said channel to said neck. 7
